To'll ziolmmt may concern.'

Be it kown'that I, JOHN U. Jonas, a citizen of the Unitedk States of America, residing at Dallas, in the county. of Dallas and.

State -of Teiras, have invented certain new and useful Improvements in Engines, of which the following isa specification.

`This invention relates to 'new 'and useful.

improvements in engines. l

The object of the invention is to provide vauengine or motor which maybe operated by oil, air or steam or anyv combination of these mediums. i

A further objectJ is-to-l rovide an engine for use' in conjunctlon wit the valve device forming the subject matter of my applicationserialNo. 658,331.

in structure.

A particular object isto provide a coinbination engine which may be manufactured in 'standard 'sizes and readily i converted from'A one fuel tol' another `withouta change 'A very important object is @to obtain. a greater capacity and more power in the same sizejof cylinders, pistons and other'k arts, nowy manufactured for predetermined i orse power, as well as obtaining greater The invention will be more readily iinder StOQd *..IOII a' reading .of 'the following` specification and by reference to the accomeconom and 'continuity of service. Anot er object 1s to'provide 'a combination oi-l 'and steam engine ;1n which the steam in the cylinder is superlieated vby Vex-f" change'with the radiation 'from the piston' and whereby the piston is cooled and an auxiliary pistonA cooling medium is thus elin'iinated.,V

A construction 'designed to out the invention will be hereinafter described to? gether with other features of Ithe invention.

' Fig. 9 is'a cross-sectional view on the line 9 9 of Fig. l, l j i l Fig. 10 is a fragmentary longitudinal cross-sectional view of a modified form of. engine-'and y Fig'. 11 is a detail of the fluid inlets. f In'the drawings the numeral -10 designates the cylinder of 'a double acting engine surrounded by a cooling jacket ll which may be' suitably lsupplied and' maintained. A pistonhead 12 is slidable in the/'cylinder yand has suinps 13 in each end. The cylinthe head is surrounded by aheating jacket- 16 Theja'cket lil-fis suitably connected with the circulating 'cooling' means usually l employed in engines of this type'. Suitable means' for supplyinglsteain or other heating fluid is connected with the chamber 15 and jacket 16.

The Jhead. 1has fanelbow 17 cast therein surrounded by the chamber 15. The "head 16y also has an elbow 18 casttherein,

'saidl elbow being provided'.witli a central bore 19, axiallyoftlie cylinder 1D andex- -tending through a sleeve 20 cast on the el bow. fA piston rod 21-e'xtends from the iston l2 through its bore19 and is surroun 'ed by4 packing rings 22 sealed in the bore. 'The l head 16 has a' cooling space 23 exposing the elbow. An extension 24 has a flange 25 by Y which itis secured to tliefliead 16.

the cylinder.A Fluid ducts 28 also extend `through/the.elbo'i'vv and openen the face of the hea/d 16 within tbe cylinder. The lelbow. 17' has' acentral fuel duct'29 and fluid ducts '30 yo'nfeach side thereof. In the cylinder end of the yduct 294 is screwed an atomizing head. (Figs. land '5) composed ,of a disk 31` and through radial ynozzles' 32. i The headl'has a boss 33, while the' head screwed an atomizing nozzle 27 directed into.

l16 has a similar boss -34 at one side. Each t boss and bead has an inwardly tapered radial vso g i t l 1,680,605"

borveyili.` for receivingliditapered valve casin 36 which -iits tightly therein and Y1s provlde with. an voutwardly 'directed flange 37 by whichv it isfa'stened to the boss. The valve l mechanism foreach head isthey same and a description of one will explain both. This mechanism is substantially the same as that described in my copending application here- .inbeforereferred to." Itl will be noted that 'the lower end ofthe Valvecase issurroundedI by the cooling jacket 16T of the head.l

. ards 47r'moun'ted on theiiange A roller v 51 surrounds the stem betweenfthe end of" the tube andgthe collan* This spring nor-v !.lo mailly'holdsfthe valve head`43 against 'thewardly a` short distance. 4At the inner end of thetube I provide a valve chamber 39= into which is-screwed a seat ring 40 (Fig.; v3) ywhile at the other end ofthe chamber is formeda valve seat 41'. The chamber' thus has valve seats at each-fend, thebore of the ring' communicating with the duct 26 or 29,

as, the case may be, A- valve stem '42 extends Athrough the'tube and-husa valvev head 43 thereon. disposed inthe chamber 39. The headis .dressedon both' ends sol-as to engage the ring's'eat ,when moved inwardly and to' engage the seat 41 when moved outwardly.

The valve stem extends through a stutiingbox 44 att-he outer end of the'tube.- A cap 45 is vfastened on the end-of the stem and isv4 slidablefin a cross bar 46 carried byv stand- 48 is journaled in -thelcap and engagesl an' eccentricAQ, an element ofalvalv'e operatingl as means forming no part of .this invention.

The; tube within.. the valve case' is' sur-f rounded byra vertical.' annular chamber '54'.
